Really odd one: parts of global DNS just dropped off the map

Forwarding was promoted because it could decrease Internet bandwidth.
Duplicate DNS requests from multiple servers could be answered by the
cache that is being forwarded to. The problems in forwarding DNS
queries, along with the increase in bandwidth, doesn't seem to make
forwarding as useful as maybe it was at one time. But, old ideas and
documentation dies slowly.
I can think of at least one reason that could require forwarding. If
you are on an internal network that has servers that provide an
"internal" DNS view, then going directly to the root servers would not
provide access to this internal DNS information, so forwarding would be
necessary. (I'm not saying that a better solution wouldn't be to make
this server a slave to the internal zone(s), but this may not be
possible for multiple reasons.)
You are taking a very undeserved shot at MCSE's. I know of both
excellent, and lazy, MCSE's. I also know of both excellent, and lazy,
DNS administrators running BIND. Please don't attack the MCSE program
with such a broadside, it is undeserved. (Further comments about this
should be taken off-line.)
